Before undertaking to write the history of the manners and morals of this period in action, the author of this Study has patiently and minutely examined the principal reigns in the history of France, the quarrel of the Burgundians and the Armagnacs, that of the Guises and the Valois, each of which covers a century. His first intention was to write a picturesque history of France. Three women--Isabella of Bavaria, Catharine and Marie de’ Medici--hold an enormous place in it, their sway reaching from the fourteenth to the seventeenth century, ending in Louis XIV. Of these three queens, Catherine is the finer and more interesting. Hers was virile power, dishonored neither by the terrible amours of Isabella nor by those, even more terrible, though less known, of Marie de’ Medici. Isabella summoned the English into France against her son, and loved her brother-in-law, the Duc d’Orleans. The record of Marie de’ Medici is heavier still. Neither had political genius. It was in the course of these studies that the writer acquired the conviction of Catherine’s greatness; as he became initiated into the constantly renewed difficulties of her position, he saw with what injustice historians--all influenced by Protestants--had treated this queen. Out of this conviction grew the three sketches which here follow; in which some erroneous opinions formed upon Catherine, also upon the persons who surrounded her, and on the events of her time, are refuted. If this book is placed among the Philosophical Studies, it is because it shows the Spirit of a Time, and because we may clearly see in it the influence of thought. But before entering the political arena, where Catherine will be seen facing the two great difficulties of her career, it is necessary to give a succinct account of her preceding life, from the point of view of impartial criticism, in order to take in as much as possible of this vast and regal existence up to the moment when the first part of the present Study begins. Never was there any period, in any land, in any sovereign family, a greater contempt for legitimacy than in the famous house of the Medici. On the subject of power they held the same doctrine now professed by Russia, namely: to whichever head the crown goes, he is the true, the legitimate sovereign. Mirabeau had reason to say: “There has been but one mesalliance in my family,--that of the Medici”; for in spite of the paid efforts of genealogists, it is certain that the Medici, before Everardo de’ Medici, _gonfaloniero_ of Florence in 1314, were simple Florentine merchants who became very rich. The first personage in this family who occupies an important place in the history of the famous Tuscan republic is Silvestro de’ Medici, _gonfaloniero_ in 1378. This Silvestro had two sons, Cosmo and Lorenzo de’ Medici.
